I actually didn't mind that so much. It was a short scene and it didn't feel too shoehorned in. Unlike the Maul scene in Solo. That was just shit for the birds. He ignited a lightsaber for not other reason than for dorks to slobber "Oh cool, a light-thaber! DERP!!!!"
If they're really going to have Dawson play Ashoka, it's not going to just be a minor bit.
